To all whom it may concern:

Be it known that 1, WILLIAM C. STEWART, a subject of the King of Great Britain, and a resident of Lynn, in the county of Essex and State of Massachusetts, have invented an Improvement in Jacks for slugging and other Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The invention to be hereinafter described relates to acks for slugging and other machines, and has for its general object the provision of means whereby the heel to be slugged may be presented at the proper angle to the driving instrumentalities.

The further aims and purposes of the invention will best be made clear from the following description and accompanying drawings of one form of means for carrying the invention into efiect, the true scope of the invention being definitely set forth by the claims.

In the drawings: Figure l is a side elevation of a jack or shoe support embodying the present invention, parts being broken away to show structures beyond; and Fig. 2 is a section on line 2-2, Fig. 1.

Referring to the drawings, the supporting frame 1 may be of any usual character and project as an arm from the frame of an ordinary slugging or other heel nailing machine having usual or desired forms of slugging or nailing devices, which, forming no part of the present invention, need not be shown and described.

Screw-threaded into the supporting arm 1 is the post 2 havin a hand wheel 3 by which it may e rotated to thereby adjust its vertical height. *rojecting upward from the post 2 is a supporting pin d which enters a socket 5 in an enlarged base portion 6 of a spindle 7, said base portion 6, by reason of the enlarged socket 5, being free, as will be obvious, to move and swing upon the upwardly projecting supporting pin t. Secured to the hand wheel 3 is the cage 8 having a central opening 9 somewhat smaller in dimensions than the base piece 6 so that while the base piece 6 and spindle 7 carried thereby may freely slide and tilt upon the supporting pin a, the cage 8 limits such freeing movement and prevents the disengagement of the base piece from its sup porting pin In order that the parts may be readily assembled and then held in the relation hereinbefore indicated, the cage 8 is secured to the radial spokes 10 of the hand wheel 3 by means of detachable securing devices, such as the screw bolts 11.

The upper portion of the spindle 7 is provided with a socket 12 in which is received the lower end portion of a last supporting pinfll t jljhe last.supporting pin 13 is preferably formed somewhat conically at its lower portion, as indicated in Fig. 1, its lower end 1% being smaller than its upper portion 15, so that said last supporting pin 13 may readily be tilted in any direction, as will be obvious. The bottom of the socket 12 may be provided with a supporting piece 16 on which the lower end let of the last supporting pin may bear and over which it is readily movable, as hereinbefore inclicated. Disposed above the upper end of the conical portion of the last supporting pin is a collar 17 against which the cone or crown of the last 18 may rest, and between said collar and the upper portion 15 of the conical end of the last supporting pin there is a groove 19 adapted to be engaged by the end of a spring 20 secured at 21 to the spindle 7, the construction being such that while the last supporting pin 13 may readily tilt in any direction with respect to the spindle 7, and thereby change the angular position of the heel 22 with respect to the slugging or other nailing instrumentalities, said last supporting pin may not be readily detached from its spindle '7, it being understood that the spring 20 in no manner interferes with the free tilting of the last supporting pin and that the lower end 1a of the lastsup porting pin rests in all positions on the bottom of the socket 12 in the spindle 7.

While the spindle 7 and its enlarged socketed base and last supporting pin connection with the post 2 will permit the shoe to be moved and tilted within certain limits, it will be evident to those skilled in the art that under some conditions this tilting action will not sufiice for the proper direction of the slugs through the toplift, and that the provisions herein made will permit the desired angular adjustment of the work with respect to the slugging or other nailing instiumentalities; and it will likewise be evident that, regardless of the fact that the last pin socket in the last is not always centrally disposed thereof, the free universal connection between the last supporting pin and spindle will permit the proper positioning of the lasted shoe, notwithstanding such fact.

Obviously various changes may be made in the form and character of the parts within the true scope of the present invention and various forms of last supporting pins may be employed, it being understood that the present invention contemplates a construction wherein capacity for proper positioning of the heel with respect to the slugging or other nailing means is made possible.

What is claimed is:

1. In a jack for slugging and other machines, the combination of a supporting post and spindle, a loose socket and pin connection between the post and spindle, said spindle at its upper end being provided with a socket extending longitudinally thereinto, and a last supporting pin freely tiltable at all times in said spindle socket and having its end within the spindle socket resting on the bottom thereof.

2. In a jack for slugging and other machines, the combination of a supporting pin, a spindle having an enlarged socketed base portion free to slide and tilt on said pin, and a cage for retaining the spindle base portion on said pin, said cage extending over the base portion and having an enlarged opening through which the spindle extends.

3. In a jack for slugging and other machines, the combination of an adjustable post having a supporting pin, a spindle having an enlarged socketed base portion free to slide and tilt on said pin, and a cage for retaining the spindle base portion on said pin, said cage extending over the base portion and having an enlarged opening through which the spindle extends.

4. In a jack for slugging and other machines, the combination of a post and spindle, a loose socket and pin supporting connection between the post and spindle permitting the spindle to freely slide and tilt with respect to the post, said spindle having a socketed upper portion extending longitudinally into the body of the spindle, and a last supporting pin having an enlarged bearing portion adjacent the upper end of the socket and a smaller end portion bearing upon the lower end of the socket.

5. In a jack for slugging and other machines, the combination of a post and spindle, a loose socket and pin supporting connection between the post and spindle permitting the spindle to freely slide and tilt with respect to the post, said spindle having a socketed upper portion, a last supporting pin loosely sustained in said socketed portion and free to tilt therein, and means to detachably retain the last supporting pin in said socketed portion.
